9.9.2 Disable Mode 

9.9.2 Disable Mode 

In disable mode, the module will neither transmit nor receive. In this mode the internal clock is stopped unless the module is active. If the module is active, it will wait for 11 recessive bits on the CAN bus, detect that condition as an IDLE bus, and then accept the module disable command. The WAKIF interrupt (wake-up interrupt) is the only CAN module interrupt that is active in disable mode.
